is there a company that sells a packaged set of every light bulb we would need (by X5 year / model) to complete this upgrade?

No. Just order from superbrightled's and for the flank 194's, just order these:

Your 2006 should be the same as my 2005. I don't understand the fascination of "kits". I have detailed what bulbs you need and even provided links on where to purchase them. Kit's are often older LED technology and way more expensive. If you really want to go cheap, order LED's off eBay and wait 4 weeks. Some of the best LED's have come from China and Singapore (purchased from eBay)

cool thanks brother!

I actually sell LEDs in my area, and here's a run-down of what you need:

No-error bulbs:
2- T10 (or standard bulbs that you'll have to wire a resistor in-line for, for mirror lights)
2- 36-39mm festoons (I recommend the 39mm, as they usually have one more LED, and therefore less resistors that make unnecessary heat). With the no-error festoons, make sure you get ones WITHOUT a heatsink, as they will not fit in the housings.

Standard bulbs:
4- T10 spot (for map lights)
4- T10 360 (for domes and trunk lights)
11- 36-39mm festoons (for floor, under dash, under doors, sunvisors, and glovebox)


To change the mirror ones, go buy yourself a set of plastic pry tools. It will make the job much easier, trust me.

papasmurf - thanks for your post. Sent you a PM.
